Built to Series 6530 specifications, it features a 140-degree drill point angle optimized for penetrating hard and abrasive materials with reduced thrust force. The EgiAs finish improves surface hardness and heat resistance, extending tool life in high-cycle production environments. The drill includes an X-Thinned web for improved chip evacuation and reduced cutting resistance. At 0.3125 inches in diameter with a 10xD flute-to-diameter ratio, it supports through-coolant delivery to maintain cutting edge temperature during deep-hole operations.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for CNC machining centers, drill presses, and manual milling setups where taper length reach and chip clearance are required. The straight-cylindrical shank and 5\/16-inch shank diameter allow direct mounting in standard collets and drill chucks. It is intended for use by machinists and tool-and-die professionals working in aerospace, automotive, die-and-mold, and general precision manufacturing environments where consistent hole quality and tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust and improves centering on entry\u003c\/li\u003e\n  \u003cli\u003eEgiAs finish provides enhanced heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable for deep-hole drilling and extended run cycles\u003c\/li\u003e\n  \u003cli\u003eX-Thinned web promotes efficient chip evacuation and lower cutting forces\u003c\/li\u003e\n  \u003cli\u003e10xD flute-to-diameter ratio delivers taper length reach beyond standard jobber drills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OSG Series 6530 taper length drill for use in standard straight-shank collets and drill chucks accepting a 5\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable safety procedures. Ensure the collet or chuck is clean and the shank is fully seated before tightening. Through-coolant supply lines should be verified for proper pressure and flow before initiating deep-hole cycles. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tool failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 105 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 10xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 155 mm (approximately 6.1 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: X-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6530\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.15 inches L x 0.55 inches W x 0.4 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 653031212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753081798962,"sku":"653031212","price":323.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87f7ff7c8fa7b0a8efc9ab21e88b1f0e_78c4d075-531e-454c-8790-738b9965629d.jpg?v=1788932636","url":"https:\/\/voomisupply.com\/products\/osg-653031212-taper-length-drill-0-3125-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
